+Simple examples with ``tox.ini``
+================================
+
+These examples provide necessary configuration to:
+
+* aggregate coverage from multiple interpreters
+* support tox parallel mode
+* run tests on installed code
+
+The `adhoc` layout is the old and problematic layout where you can mix up the installed code
+with the source code. However, these examples will provide correct configuration even for
+the `adhoc` layout.
+
+The `src` layout configuration is less complicated, have that in mind when picking a layout
+for your project.
